Can anyone tell me how to hook up the in dash brake controller. Has a trailer gain in the info gauge. Doesn't seem to work though. Did notice a wire under the hood by the master cylinder that has a terminal loop on it. Does this need to be hooked up to a power post to activate the controller?

If you have the integrated controller, it is ready to go. You don't happen to have electric / hydraulic on your trailer do you? Compatible with electric only...

 

The wire under the master cylinder is for the 12V+ pin in the trailer connector. It goes to stud one on the fuse block. Your trailer may need this hooked up to activate the brakes. It is a 40A fused circuit.

 

If you don't have the integrated controller, you need to hook up the wire behind the fuse block to stud 2, then tie the after market controller into the wiring that is blunt cut and taped up under the dash.

 

Mine works great - just had to adjust the gain a bit.

You should not have to do anything - take it back to the dealer and have them fix it. There is both a blue and orange wire going from the fuse box in the engine compartment the blue one goes to the trailer brakes, the orange is +12V to charge the battery. Both should be attached to fuses inside the box. They should have been installed at the factory.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.
